A Thermodynamic approach of the aqueous-phase glucose reforming reaction for hydrogen production: A comparative study with glycerol and ethylene glycol

Abstract

In the present work is reported for the first time the thermodynamic analysis of aqueous-phase glucose reforming. The reaction has been studied at low temperature values (298-338K) and at atmospheric pressure with the reactants to be in liquid phase and the products in gas phase. For the calculations it is considered the Van't Hoff's equation and the case that the two phases (liquid and vapor) are in equilibrium. According to the results temperature increase affects positively the conversion of glucose to hydrogen. Comparable with glycerol and ethylene glycol which are also considered being among the most promising sources for hydrogen production, glucose gives the highest conversion.
